Kappa Shader v3.1 Preview E1 (Patreon)

Oi, this preview is a bit outside of my initial schedule but I came up with a couple minor additions that seemed nice.

- added localized cloud coverage- added cloud shadows- redid out of the box color grading- atmosphere adjustments- added sun disc to the end- adjusted volumetric fog- improved auto exposure behavior- minor improvements to cirrus clouds- improved global illumination- reduced RSM bleeding- improved water waves- added various new settings- added support for anamorphic depth of field (currently only in full version)
